Why Investigate CAM?
ƒ Patient driven
ƒ Not all conventional therapies 100% effective
ƒ Supposedly non-toxic
ƒ Many tumors are not organ-confined:
Holistic Approach
What to Look for in Natural Therapies
• A known mechanism of action
• Evidence that it relieves symptoms
• Demonstrated safety
• Quality of Product
• Low cost
• No interaction with other meds

Target Populations for Prevention
in Your Practice
• Primary Prevention:
• African Americans
• Family History
• High Grade PIN
• Secondary Prevention:
• Elevated PSA, Negative biopsy
• Post-RRP/Radiation with Rising PSA
All Men Over 40 are at Risk!!
Prostate Cancer Development
• Linked to Inflammation
• Many men have prostatitis on biopsy
• Cancers linked to Inflammation:

AHCC
(Active Hexose Correlated Compound)
1. Very low-molecular-weight (5,000Da), highly absorbable alphaglucan-rich compound
2. Produced from enzymatically fermented mycelium of Japanese medicinal mushrooms
3. Clinical shown to have strong immunomodulating properties
• Increase NK cell activity
• Increase number and activity of DC cells
• Increase cytokine response
4. Research
• 24 Pubmed-listed studies published in peer-reviewed journals
• Numerous other studies published in Japanese journals
5. Clinical Use: in over 1,000 clinics and hospitals, primarily in Asia
1. Primary Care Clinics (immune support and prevention)
2. Cancer Clinics (immunotherapy reduction of chemo side-effects)
3. Hospitals (reduction of hospital borne-infections)
4. Hepatology Clinics (reduce viral loads in Hep-C patients)
AHCC and NK Cells
• Significantly increases NK cell activity in immune
compromised patients
• Stimulates T-cells, macrophages and increases cytokines
• Increases activity and number of DC cells
• Appears to be able to stimulate and modulate because it
works on both the macrophages and the cytokines:
valuable links and network messengers
• Built in dampening system; can be taken continuously and
does not need to be stopped like other immune-enhancing
supplements
AHCC Research: Select Published Animal Studies
▪ Infections: influenza20, west nile virus15, bird flu11, MRSA19
▪ Tumor necrosis, improved survival of tumor-bearing mice
▪ Reduced side-effects of chemo8 & non-interaction with chemo3
▪ Anti-inflammatory properties (colitis26; diabetes13)
▪ Auto-immunity (Amyotrophic Lateral Sclerosis (ALS)12)
▪ Protective effect on bone marrow9 , thymus gland7, liver22, spleen8)
▪ Enhanced activity of NK cells, T-cells, macrophages, cytokines
AHCC: Select Published Clinical Studies
▪
269 liver cancer patient prospective cohort study (1992-2001) showed longer “no
recurrence” period and increased survival rate (Journal of Hepatology)33
▪
132 stomach cancer patients showed enhanced 5-yr survival rate34
▪
44 liver cancer patient placebo-controlled study showed prolonged survival and
improved Quality of Life36
▪
30 healthy elderly patient study at Yale Medical School showed increased cytokine
production (TNF-γ and IFN-α) 4
▪

ƒ ProstaCell contains this antioxidant with
highest capacity for scavenging free radicals1

Lycopene: Epidemiological Data
ƒ Dietary consumption of lycopene associated with a
decreased cancer risk 1
ƒ 35/ 72 studies demonstrated a significant decrease in
risk1
ƒ The largest study found that 2-4 servings of tomato
sauce per week was associated with a reduction of
35% in the risk for CaP2

- Phase II randomized clinical trial
- ↓ involvement of surgical margins, ↓ extent
of HGPIN as well as ↓ in tumor size

Soy Isoflavones
ƒ Properties
ƒ Active metabolites: genistein and daidzein
ƒ Adventist Health Study, 1998
↓ CaP risk1
- consumption of soy milk
ƒ Genistein has been shown to:
- Reduce DNA synthesis in LNCaP cells
- Inhibit the effect of testosterone in development of
CaP in rats2
